[PATCH net v1] net: mscc: ocelot: fix stat counter register values

[Colin Foster]

Commit d4c367650704 ("net: mscc: ocelot: keep ocelot_stat_layout by reg
address, not offset") organized the stats counters for Ocelot chips, namely
the VSC7512 and VSC7514. A few of the counter offsets were incorrect, and
were caught by this warning:

WARNING: CPU: 0 PID: 24 at drivers/net/ethernet/mscc/ocelot_stats.c:909
ocelot_stats_init+0x1fc/0x2d8
reg 0x5000078 had address 0x220 but reg 0x5000079 has address 0x214,
bulking broken!

Fix these register offsets.
